The eSim's are available these days so you don't have to wait for new SIM to arrive... if your provider & phone supports this feature.
With a normal SIM all you need is the device you're going to put it into. And a needle/paperclip...
You just need an internet connection to get the QR code for the esim (though I have a paper version I can scan as well). The beauty is I don’t have to swim to the bottom of a lake to get the original phone to get the original sim. I can just scan the piece of paper and put my pin into the new phone. Though I think no matter what, I would have to go online to give the IMEID so the phone will successfully activate.
